Answer:
yes they do
Explanation:
Acquired characteristics, by definition, are characteristics that are gained by an organism after birth as a result of external influences or the organism's own activities which change its structure or function and cannot be inherited.

What is metabolism?
Metabolism refers to the chemical processes that occur within a living organism in order to maintain life. These processes include the conversion of food into energy and the use of that energy to power the organism's growth, reproduction, and other functions.
Metabolism can be further divided into two main categories: catabolism and anabolism.
Catabolism is the process by which the body breaks down molecules to release energy. It includes the breakdown of complex molecules such as carbohydrates, fats, and proteins into simpler molecules that can be used by the body's cells for energy. This process produces waste products such as carbon dioxide and water which are eliminated from the body.
Anabolism is the process by which the body uses energy to build molecules. It includes the synthesis of complex molecules such as proteins, nucleic acids, and polysaccharides from simpler molecules. Anabolic reactions consume energy, rather than release it, and they require precursors and enzymes.

Why do organisms that fertilise internally tend to produce less eggs?
Answer:
Explanation: Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. The embryo is isolated within the female, which limits predation on the young. ... Even though fewer offspring are produced through this method, their survival rate is higher than that for external fertilization.

So pepsin is basically a gastric juice which is produced in the stomach.
v-FLIPs are viral proteins that were first identified as modulators of apoptosis; they contain two death effector domains, which are also found in some initiator caspases such as procaspase-8. These v-FLIP proteins can be recruited to the DISC through the binding of the death effector domain to similar domains in the adaptor proteins but are otherwise catalytically inactive. What do you think is the effect of v-FLIP expression in the host cell?A. It promotes apoptosis mainly via the extrinsic pathway.B. It inhibits the extrinsic pathway of apoptosis.C. It activates only the mitochondrial pathway of apoptosis.D. It inhibits the intrinsic pathway of apoptosis.E. It enhances the caspase cascades in both the intrinsic and extrinsic pathways.
Answer:
B. It inhibits the extrinsic pathway of apoptosis
Explanation:
Apoptosis is a cellular pathway that leads to programmed cell death. Viral FLICE-inhibitory proteins (FLIPs) bind to the adaptor proteins and block the interaction between the DISC complex with the caspase-8 protease enzyme, which triggers apoptotic cell death. In consequence, cells become resistant to Fas-mediated apoptosis, a pathway initiated by the FADD protein which is known to recruit caspase-8.

Answer: The cell cycle has two major phases: interphase and the mitotic phase (Figure 1). During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides.

Explanation:
Bat wings, a human hand, and a whale flipper are all ________________structures. Explain WHY?
Butterfly wings and bat wings are examples of _______________ structures.
The mouths of horseflies and mosquitoes are examples of _______________ structures.
A _______________ structure is one that does not currently have a function in the organism. Give an example.
Comparing structures of embryos is an example of __________________.
If embryos share a common structure, what does that say about their evolutionary relationship?
How would the protein sequence of two closely related species compared to the protein sequences of two unrelated species? Give an example of each here.
Answers:
1.blank: Homologous
why?: They all have similar structures passed on from a common ancestor. Although they all have different functions now, they still all have the same basic pattern of bones.
2.blank: Analogous
why?: Butterflies and bats are both unrelated organisms but they both have similar structures. However, unlike homologous structures, analogous structures do the same job (help the organism fly) but are structured entirely differently because they evolved in the two species independently and did not share a common ancestor.
3.blank: Homologous
why?: (see question 1 ^)
4.blank: Vestigial
example: An example of a vestigial structure is a human's tail bone.
why?: Over time humans evolved and our tail bones shrank as we adapted. While we still have one, it serves no purpose in our lives today.
5.blank: Embryology
why?: Embryology is the branch of science and medicine that is focused on the development and study of embryos. Scientists in this field study the prenatal development of gametes, fertilization, and development of embryos and fetuses.
6.answer: They share a common ancestor
why?: Embryos of many different species can show evidence of sharing a common ancestor based on the similarities and structures of them all. Similar structures during development support common ancestry. For example, all vertebrae embryos develop gill slits and tails but not all develop into those structures. Over time as organisms evolved their structures changed with them.
7.answer: If the protein sequence of two species is closely related the two species are most likely similar, but the protein sequences of two unrelated species are not similar meaning these two species are very different. By comparing the positions of amino acids on protein chains you can determine how similar the species are. The less different the positions are, the more alike and related they are.
why?: For example, humans and chimpanzees only have one position on the amino acid chain where they are different but if you compare humans and moths there are 31 different positions.

Come up with five ethical guidelines for research. Write statements that reflect your own views of
what is right and wrong. If you really love animals, an example of one guideline might be "No
animals may be used in research of any kind." However, when coming up with these guidelines, be
thoughtful about what they really mean. Think of the information you read about earlier. Try to
phrase your guidelines in a way that would allow research that you think would be beneficial to
still be done. You may find that certain circumstances may cause you to rethink your own ethics!

Answer:
Glycolysis occurs in the Cytoplasm
Electron Transport Chain occurs in the Mitchondria
Krebs Cycle also occurs in the mitchondria
Explanation:
Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. Nearly all living organisms carry out glycolysis as part of their metabolism. The process does not use oxygen and is therefore anaerobic. Glycolysis takes place in the cytoplasm of both prokaryotic and eukaryotic cells.
The electron transport chain is the last stage of the respiration pathway. It is the stage that produces the most ATP molecules. The electron transport chain is a collection of carrier proteins found on the inner membrane of mitochondria. NADH hydrogen ions and electrons into the transport chain.
The Krebs cycle happens only within the mitochondrial matrix. Pyruvate is formed in the cytosol of the cell, then imported into the mitochondria.
